This invention relates to bhe manuaetui'e rf tires of the open-bellied type and has for object 'pzjevide e. device which will i' lif 'y the laying en of the fabric and .hieh'will premee the symmetrical buildu: es the tire Apen tbe core so that the rie "will be properly stfetcbed :is Jhe mold mees upon it. in the. press te ebviate ibinkles which eonsitute one of the mest struction at the present time. e in bi'i'ilding tires, it is old to initially Space the sides of the tire fret i the sides of .me ring core upon which che tire is built and ie is else old eo embed en iii-extensible ing formeel of a pluraliy of ini-ns of Wii'e :i each beati of the tire While the tire is miflei c-.enstru'ciom li; is old to subse- -zpxeilllv prees be straight sides; of the tire io miiffxnfin to the inemvecls'sies of the cere by 'libe epplieetionc the sie plaes ofi e meld. if ;Y n'ire'iings being inexeisible maintain you the tire.

To resist ietortioii ef the flange, the Seeiems are fein'osce by webs which bridge lie angle between the inner face of lie emi the top fece or the inner leflge 13.

ln buiiiug the ii'e upc-n e eore equippe wili lie above (iesciibed izmges, tliesue cessive layers 0itii'e ebrie are initially ep plied meielly G the eown of the core l() and' then pressed at the sides egeine the straight parallel langes 17, the leyei's being ieete at the'edges to confine the wire reinorcingmings 2G and te form the beacl l5 of lle tire. qWhile the tire is under construction, the outer ledges 23 support and maintain the wire ringsand beads Aconcentric with the axis of the tire. The Working faces 27 of the outer ledges of both flanges extend in a plane that is perpendicular to the plane of the core, thus insuring that both sides of the-tire Will be built symmetrical. Preparatory to the application of ythe mold the flanges are removed from the core. Since the Wire rings are inextensible, they maintain their own diameter and carry the beads in a straight line when the mold closes upon the tire in the press, instead of in an arc, such as shown at 28, whereby a stretch is imparted to the sides of the tire corresponding to the distance between the arc 2S and the rib 14 of the core, thereby obviating all Wrinkles and `insuring a uniform tension throughout the sides of the tire.

While I'have illustrated and described the particular construction of the straight flange, l do not limit myself to the exact construction shoiv'n, it being only necessary to the practice of my invention that a flange be employed which is provided on the outer face With a ledge for supporting and positioning the bead of the tire concentric with the axis of the tire while the tire is under construction.

Having described my invention, what I claim and desire to protect by Letters Patent-is:

l. A tire building machine embodying a ring core having incurved sides, removable flanges on the core having parallel outer faces extending over said incurved sides in the outer planes of the core, and annular ledges on the outer faces of the flanges disposed adjacent to said sides and concentric With the axis of the core.

2. A tire building machine embodying a ring core having incurved sides and having annular ribs contiguous with said sides,

flanges on the sides of the core extending parallel u ith the plane of the core, and annular ledges on the outer faces of the flanges having their outer peripheries in alinement with the outer peripheries of the ribs.4

3, A tire building machine embodying a ring core having incurved sides and having 4ribs contiguous with said sides, flanges on the sides of the core extending parallel with the plane of the core, and annular ledges on the outer faces of the flanges disposed adjacent to said ribs and having their outer peripheries extending in a plane which is perpendicular to the plane of' the core. Y

l. A tire building machine embodying a ring core having incurved sides and having annular ribs contiguous with said sides7 flanges on the sides of the core extending parallel With the plane of the core, and annular ledges on the outer faces of the flanges having their outer peripherics extending in alinement with the outer periplieries of the ribs and extending in a plane which is perpendicular to the plane of the core.

-A tire building machine embodying a sectional ring core having incurved sides, annular ribs contiguous with said sides, clamp rings below the ribs removably securing the sections of' the core together, annular flanges extending over said incurved sides, ledges on the inner faces of the flanges abutting against the outer faces of the ribs and against the top faces of the rings, means removably securing the flanges to the rings, and ledges on the outer faces of the flanges concentric with the axis of the core.
